The release of 116 rare photographs from the Auschwitz concentration camp are yet another reminder of the power of photographs to illuminate human history. We have these treasures because of the work of dedicated librarians and photoarchivists in the last century. Even in the age of digital photography, our photos won't live on without cataloging and captioning.
